to a new type of microscope,
un nou tip de microscop,
like a regular microscope
precum un microscop obişnuit
and image processing
şi procesarea imaginilor
and color changes in objects and people,
for us to see with our naked eyes.

in a completely new way.
ȋntr-un mod cu totul nou.
changes its color very slightly
ȋşi schimbă culoarea foarte puţin
look at other people,
sitting next to you,
la persoana care stă lângă tine
or their face changing color.
schimbându-și culoarea.
it appears to us like a static picture,
ȋl vedem ca o imagine statică,
through our new, special microscope,
prin noul nostru microscop special,
a completely different image.
o imagine cu totul diferită.
in the color of Steve's skin,
ale culorii pielii lui Steve,
so that they become visible.
pentru a deveni vizibile.
Steve's heart is beating,
cât de repede bate inima lui Steve,
that the blood flows in his face.
curge sângele prin faţa lui.
to visualize the pulse,
nu doar ca să vizualizăm pulsul,
recover our heart rates,
şi fără să atingem pacienţii.
and without touching the patients.

este la fel de precisă
with a standard monitor in a hospital.

with other videos as well.
şi cu alte video înregistrări.
din filmul „Batman – Începuturi"
from "Batman Begins" here
he's wearing makeup,
we're able to extract his pulse
am reușit să extragem pulsul
in the light that are recorded
în timp
so that we can see them.
ca să le putem observa.
are extremely subtle,
sunt extrem de subtile
when you try to separate them

image processing techniques
de procesare a imaginilor
of the color at each pixel in the video,
a culorii fiecărui pixel din video
changes over time,
of enhanced videos, or magnified videos,
clipuri ȋmbunătăţite sau amplificate
not just to show tiny changes in color,
nu doar pentru schimbări infime de culoare
that gets recorded in our cameras
ȋn camerele noastre
of the object changes,
culoarea obiectului se schimbă,
when she was about two months old.
about three years ago.
to make sure our babies are healthy,
că ne sunt sănătoşi copiii,
that they're alive, of course.
pentru bebeluşi
when she was asleep.
with a standard baby monitor.

there's not too much information there.
dar nu ai prea multe informaţii.
sau mai folositor,
or more informative, or more useful,
at the view like this.
and I magnified them 30 times,
şi le-am amplificat de 30 de ori.
era cu adevărat vie și respira.
daughter was indeed alive and breathing.
in the original video,
nu vedem prea multe,
the breathing becomes much more visible.
respiraţia devine mult mai vizibilă.
a lot of phenomena
cu noul nostru microscop de mişcare.
with our new motion microscope.
are pulsing in our bodies.
pulsează ȋn organismele noastre.
are constantly moving
right after my daughter was born,
la scurt timp după ce s-a născut fiica mea
too much sleep. (Laughter)
că nu prea reuşeam să dorm.
we can extract
small facial expressions.

mechanical movements,
and diagnose machinery problems,

sway in the wind and react to forces.
şi reacţionând la forţe.

ştie să le facă ȋn diferite moduri,
este una,

others could use and experiment with it.
even created this nice website
au şi creat un website
and process them online,
și procesa videourile online,
in computer science or programming,

cu acest nou microscop.
with this new microscope.

and then magnified their motions.

all those examples
acest nou instrument,
a new way to look at the world,
new and creative ways of using it.
creative şi interesante de a-l folosi.
to look at the world in a new way,
să privim lumea cu alţi ochi,
we can do with our cameras.
ce putem face cu camerele video.
am ȋnceput să ne ȋntrebăm
produce tiny motions
produc micromişcări
our cameras to measure?
cu camerele video?
that we focused on recently is sound.
ne-am concentrat recent este sunetul.
e compus din schimbări
is basically changes

care călătoresc prin aer.
and they create small vibrations in them,
generând mici vibraţii ȋn interiorul lor,
and how we record sound.
şi să ȋnregistrăm sunete.
also produces visual motions.
that are not visible to us
cu procesarea potrivită.
with the right processing.

nu vezi mare lucru,
you'll be able to see,
vedem mişcările şi unduirile gatului
we can see all the motions and ripples
in producing the sound.

and magnify the motions 250 times,
mişcările de 250 de ori,
how the glass vibrates
to seeing every day.
It gave us this crazy idea.
Ne-a dat ideea asta nebună.
and recover sound from video
şi să redăm sunetul din video
create de undele de sunet ȋn obiecte,
that sound waves create in objects,
back into the sounds that produced them.
în sunetele care le-au produs?
everyday objects into microphones.
orice obiect ȋntr-un microfon.

that we played in the room.
we recorded of that bag of chips.

ABOUT THE SPEAKER
Michael Rubinstein - Research scientist, GoogleComputer scientist Michael Rubinstein and his team have developed a "motion microscope" that can show video footage of barely perceivable movements, like breaths and heartbeats.
Why you should listen
Michael Rubinstein zooms in on what we can't see and mangnifies it by thirty or a hundred times. His "motion microscope," developed at MIT with Microsoft and Quanta Research, picks up on subtle motion and color changes in videos and blows them up for the naked eye to see. The result: fun, cool, creepy videos.
Rubinstein is a research scientist at a new Cambridge-based Google lab for computer vision research. He has a PhD in computer science and electrical engineering from MIT.
